ADJUSTABLE SHADE-HANGER.

Specification of Letters Patent.

Patented Nov. 16, 1920.

Application filed December 24, 1919. Serial No. 347,153.

To all whom it may concern: I I Be it known that I, EUGENE L. Hon'roN, a citizen of the United States, residing at San Francisco, in the county of San Francisco and State of California, have invented new and useful Improvements in Adjustable Shade-Hangers, of which the following is a specification. 7

This invention relates to an adjustable window shade structure.

It has been found desirable in many places of business activity and particularly in of different color for use under different weather conditions, and to thereby afford a substantially uniform illumination. It is also found that in order to produce this uniformity it is desirable to adjustably support the shade at different heights relative to the window opening. It is the principal object of the present invention, therefore, to provide an adjustable hanger upon which a plurality of various colored window shades may be mounted and from which they may be selectively unrolled at any desired elevation along the window opening.

The present invention contemplates the use of a pair of vertical tracks secured along the opposite sides of a window opening and adapted to receive sliding hangers designed to support a plurality of curtain rollers, said curtains representing different color values.

The invention is illustrated by way of example in the accompanying drawings, in which:

Figure 1 is a view in elevation showing a window frame and more particularly disclosing the application of the present invention thereto.

Fig. 2 is an enlarged fragmentary view in vertical section as seen on the line 2-2 of Fig. 1, and'showing one of the hangers and the relative positions of the curtain rollers thereon.

Fig. 3 is an enlarged fragmentary view showing one of the hangers from which the curtain rollers have been removed.

Fig. 41 is an enlarged fragmentary view showing the pulley arrangement by which the two hangers are controlled.

Fig. 5 is a sectional view through one of the hangers and its guide as seen on the line 44 of Fig. 3.

Referring more particularly to the drawings, 10 indicates a window frame carry ng suitable sashes 11 and 12. The vertical posts 13 and 1 1 of this frame are here shown as fitted with channeled track members 15 and 16. One of these members is shown in section in Fig. 1 where it will be seen to have a flat base plate 17 and over-turned flanges 18 between which hangers 19 may slide and by which they are guided in vertical paths of travel. The hangers 19 have rectangular body portions, along the opposite sides of which grooves 21 are formed to receive the track flanges 18. Substantially midway of the body is an opening 22 for receiving one of the trunnions of the curtain rollers 23, or one of the hangers. The openings are squared so that the flattened trunnions of the usual. spring shade roller will be accommodated while the opening upon the other hanger is round. The downwardly and outwardly projecting extension 24 is formed integral with the bottom of each of the hangers and extends over the face of one of the flanges 18. This extension is fitted with a roller trunnion opening 25 for receiving the trunnions of a roller shade 26. By reference to Fig. 2 it will be seen that the rotating axes of the shade rollers will be offset so that shades 27 and 28 may be easily drawn by their cords 29.

It is to be understood that the shades are of different color value, as, for example, one of the shades may be green and the other yellow, thus making it possible to properly modify the light passing into a room and to maintain a substantial uniform quality of illumination, by selecting one of the two shades and raising the hangers to a height sufficient to out out any amount of unshaded light.

The hangers are simultaneously raised and lowered by means of cables 30 and 31. The cable 30 is led over a pair of pulleys 32, fixed to the top of the window frame. These pulleys lead the cord 30 to the hangers 19, carried in the guide track 16. A pulley 33 is provided and disposed at right angles to the pulleys 32 to carry the cable 31 to hangers 19, sliding in the guide member 15. The two cables are knotted together as indicated in 34 and thus provide spaces along the cables by which the height of the rollers may be regulated as the cables hook over a pin 35, as limited by the various knots thereon.

In operation of the present invention the cables are arranged so that the hangers will be in horizontal alinement to receive the I shade rollers, the position of the hangers may then be determined by the adjustment of a cable as previously described. After this adjustment has been made, the shade of desired color may be drawn as convenience dictates and it will thus be 'seen that a portion of the light passing through the window opening will be modified, while permitting unshaded light to pass over the rollers.

It will thus be seen that the device herein disclosed, while designedly simple in its construction, provides desirable means by which the value of the li ht entering a room may be accurately regulated, both as to the screening action produced by a shade, and the position and dimensions of an opening through which unshaded light may pass. WVhile I have shown the preferred form of my invention as now known to me, it will be understood that various changes in the combination, construction and arrangement of parts may be made by those skilled in the'art without departing from the spirlt of the invention as claimed.

Having thus described my invention, what I claim and desire to secure by Letters Patent is:

The combination with the vertical sides of a window casing, of slotted guides fixed to opposite casing members, rigid hangers having slides formed on the inner faces and movable up or down in the guides, said hangershaving openings in the upper portion to receive the pivots of an upper shade roller, and having the lower portion bent at an angle with the upper portion, and projecting forwardly out of line with the upper portion, with pivot holesfor a second shade roller, and means by which the shades may be moved parallel and independently of each other.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
